Rose skeletonizer - Endelomyia aethiops

Moved

Moved from Sawfly larvae. Characteristic feeding pattern for the "slug" sawflies, and a perfect match for Cranshaw p. 83F.

Thanks

Charley. I'll collect some larvae next summer so we can get some images of the reproductive stage.

Moved

Moved from Sawflies, Horntails, and Wood Wasps.

Looks like a sawfly

- I can't take it any further than that, although Cranshaw(1) says there's one called Allanthus cinctus (curled rose sawfly) that attacks rose in the midwest - described as being "pastel green with numerous whitish spots and a yellow-orange head." He says they would be mostly curled on the undersides of leaves and do most damage when they tunnel into the stems to pupate. Does this fit yours?

Upside feeder

No, these feed on the top side. They are usually alone - occasionally in pairs - but no mass attacks. Damage is limited to the dorsal and medial layers of the leaf, leaving the ventral cell walls intact.

Another option, perhaps better:

Googling "rose sawfly" I found Calliroa aethiops described as a skeletonizer of rose leaves.

That's . . .

. . . a possible match. I'll raise a couple and see what we get. Interesting that Google doesn't yeild any images of adults.

Very good!

Wow, nice call, Hannah! It is indeed a sawfly larva, and way to track down a possible match using the host plant. Great detective work:-)

Thanks, Eric!

I don't know what I did before Google :)
